Abstract
The invention relates to a fire extinguisher filling connector which is used for connecting fire extinguisher filling equipment and a fire extinguishing bottle filling opening. The automatic stopping device is arranged in the filling connector, and when the filling nut is excessively screwed in the filling process of the fire extinguisher and contacts with the sealing shoulder of the filling nozzle of the fire extinguisher bottle, the automatic stopping device stops the filling channel, so that the safety diaphragm on the filling nut is protected from being turned backwards under the action of filling pressure (a phenomenon that the safety diaphragm is deformed towards the inner direction of the fire extinguisher bottle body under the action of external force).
Description
Technical Field
The invention relates to a fire extinguisher bottle filling joint, which is used for connecting fire extinguisher filling equipment and a fire extinguisher bottle filling port and belongs to the technical field of product structures.
Background
The automatic stopping device is not arranged inside the filling connector of the conventional fire extinguishing bottle, the filling channel inside the fire extinguishing bottle is always in a communicated state, when a filling nut of the fire extinguishing bottle is excessively screwed to be in contact with a sealing shoulder of a filling opening of the fire extinguishing bottle, the pressure of filling equipment of the fire extinguishing bottle can directly act on a safety diaphragm located on the filling nut through an internal channel of a filling structure, so that the safety diaphragm deforms towards the inside of the bottle body (commonly called as the diaphragm is reversely deformed), the normal working posture of the safety diaphragm is deformed towards the outside of the bottle body, after the diaphragm is reversely deformed once, the bearing capacity of the diaphragm can be greatly reduced, and when the design pressure of the safety diaphragm is not reached easily by the fire extinguishing bottle, the pressure is released. If the reverse hitting phenomenon occurs, the filling screw cap must be replaced in time, which causes higher resource waste; if the filling screw cap is not found and replaced in time, the fire extinguishing bottle can be accidentally disabled, and greater potential safety hazards can be caused.

The technical scheme of the invention has the advantages that: the filling channel can be cut off in time, and the phenomenon of 'reverse beating' is prevented. The automatic stopping device is arranged in the filling connector, and when the filling nut of the fire extinguisher is excessively screwed to contact with the sealing shoulder of the filling nozzle of the fire extinguishing bottle, the automatic stopping device can stop the filling channel to prevent the filling pressure from acting on the safety diaphragm through the connector.
Drawings
FIG. 1 is a schematic structural view of a filling joint of a fire extinguishing bottle according to the present invention
Detailed Description
The invention will be described in detail below with reference to the following figures and examples:
as shown in figure 1, the structure of the filling joint of the fire extinguisher is as follows: a filling nut 2 is installed at the bottom of a filling hole installation seat 1 of an extinguishing bottle through threads, a safety diaphragm is arranged at the bottom end of the filling nut 2, a square hole is processed at the center of the filling nut 2, a push rod 31 is inserted in the square hole, the square hole is connected with the push rod 31 through a square hole and a square column tenon-and-mortise structure, so that rotating torque can be transmitted to the filling nut 2 through the push rod 31, the push rod 31 is sleeved in the center hole of a base 32, the base 32 is installed on a connection surface of the filling hole installation seat 1 through threads, the connection surface is sealed through a sealing gasket I312, a nut 36 is installed at the top end of the base 32, the nut 36 is sealed with the base 32 through a sealing ring I39, a spring 33 is arranged in the center hole of the base 32 and located between the bottom of the nut 36 and the top of the push rod 31, the spring 33 pushes the push rod 31 against the connection surface in the, the connecting surface is sealed by a sealing gasket II 311, when the connecting surface is separated, the communicating pore canals in the mandril 31 and the filling nut 2 are communicated with the central hole of the base 32 to form a filling channel, a square hole is also processed at the center of the upper part of the top rod 31, a connecting rod 37 is inserted in the square hole, the square hole is connected with the connecting rod 37 through the square hole and the tenon-and-mortise structure of the square column, so that the rotating torque can be transmitted to the ejector rod 31 through the connecting rod 37, the connecting rod 37 upwards passes through the spring 33 and the nut 36 to extend out to form a rotating handle, the connecting rod 37 and the nut 36 are sealed through a sealing ring II 38, a rotary joint 34 is connected to the upper portion of the base 32, a filling hole of the rotary joint 34 connected to a pipe of a filling apparatus is communicated with a connecting hole of the base 32 to allow the fire extinguishing agent to enter the central hole of the base 32, and the inner wall of the rotary joint 34 is sealed with the outer wall of the base 32 by an upper seal ring 35 and a lower seal ring 310.
The working process of the filling joint of the fire extinguisher is described as follows:
